A PARTIAL EQUILIBRIUM LEACHING MODEL BASED ON THE KINETICS OF DISSOLUTION AND EQUILIBRIUM IN SOLUTION OF THE COMPLEX PYRRHOTITE -Fe_2(SO_3)_3-H_2SO_4 SYSTEM
Methods 0.1mol/L phosphate buffer (pH7.0) (putting water into 21.85g Na2HPO4·12H2O and 6.08g NaH2PO4· 2H2O, then dissolving and diluting them to 1000ml,mixing phosphoric acid with them to pH7.0) was taken as mobile phase in Sephadex G-10(10mm×300mm) chromatographic column. A.
The relationship between electrical potential, Cl~- content and the time during the dissolving process are ln(E-E_2/E_1-E_3)=-K_1t~(1/2)+K_2 and lnln[Cl~-]=-K_1t~(1/2)+A respectively.
The results show that when 0.5 mg/mL(10 unit/mL) of cell wall dissolving enzyme(zymolyase20T) is used in the environment of sorbitol osmotic regulator whose thickness ranges from 1.0 to 1.5 mol/L,the protoplastization rate can reach beyond 99 %,and the regeneration rate between 2 % and 11 %,and it is higher with potassium phosphate as the buffer liquid than with Tris-HCl.
The theory is applied to the case of cubic hypersurfaces, which is the one most relevant to special geometry, obtaining the solution of the two classification problems and the description of the corresponding homogeneous special K?hler manifolds.
A necessary and sufficient geometric condition on the growth of the boundary of approximate tiles is reduced to a problem in Fourier analysis that is shown to have an elegant simple solution in dimension one.
Indeed, if the coefficients of L are in $W^{1,2}\cap L^{\infty},$ then L can be rewritten in divergence form for which the notion of a "weak" solution can be applied.
QDs were embedded in the polymer beads with the specific functional groups through dissolving and swelling method, which provided the condition for the conjunction of biomolecules and QDs as fluorescent probes.
